Another post in this thread just made me step back a minute and think, why don't golf companies include a hat or shirt when you buy a set of $800 irons or a $300 driver more often? Heck every time I've ordered from JEGS (performance car parts company for those that don't know), even if it's a $50 dollar order, I get a hat. I've probably got 10 of them laying around the garage right now and I've given away more than I could ever remember. For that matter every time I had to go to the Caterpillar dealer to help pick up equipment when I was doing an internship with USACE we got a free hat or license plate. I've gotten free shirts, hoodies, hats, and other merchandise from every single company I made a large purchase with (except chevy when I bought my truck, those rats!).
It may be way off topic with what the OP was getting at but it is a good question, why aren't things like hats included when you make a large purchase from one of these companies?
On topic, I wear a mesh Bridgestone cap because it was simply designed, on sale, and finally, I don't look good in a yellow JEGS hat.....which reminds me, I need to take the goodyears off my truck and get some Bridgestone T/A's before I have two different groups of people calling me a poser.
